7 Claims.

This invention relates to a device for preventing fraud during the operation of coin-controlled mechanisms.

An object of the invention is the provision of a device which is adapted to be attachedto the coin-controlled box of a telephone or other similar coin-controlled mechanism to prevent a party Vfrom operating the telephone by means of` slugs or improper types of coins whereby the g., proper coin must be deposited before the coin can be dropped into the usual slot of the telephone receiver.

Another object of the invention is the provision of a device vfor determining in advance le. whether the coin is the right type for operating a coin-controlled mechanism before the coin can be deposited in the usual slot which sets the mechanism in operation, the device including means which will receive the coin for presenting one face of the coin to a plurality of projections which are moved into engagement with the coin and if the coin is of thel proper type these projections will cause mechanism to release the coin for depositing in the regular slot of the coincontrolled mechanism.

A further object of the invention is the provision of a device Which is adapted to be used in connection with a coin-controlled mechanism for preventing the coin or slug from being deposited in the usual slot of the housing for the coin-controlled mechanism and in which one face of the coin, due to its peculiar configuration, will be engaged by a plurality of projections which, if the coin is of the proper type, will set mechanism in operation for releasing the coin for deposit in the slot of the housing of the comcontrolled mechanism, means being employed for ejecting spurious coins to permit others to insert coins of the proper type.

'Ihis invention will be best understood from a consideration of the following detailed description, in view of the accompanying drawings forming a part of the specification; nevertheless, it is to be understood that the invention is not to be confined to the disclosure, being susceptible of such changes and modifications as define no material departure from the salient features of the invention as expressed in the appended claims.

Referring more particularly to the drawings, I0 designates generally a housing having a rear wall Il, bottom portion l2, a shelf or slide I3 and a front plate I4. The housing also includes a pair of shelves I5 and I6 connected together by a depending member I1. A plate I8 Vdepends from the front end of the shelf I6 and in cooperation with a plate I9 forms a coin slot 2B. The elements just described are connected to theside walls 2l and Zlw of the housing I0.

The housing is provided with a cover plate which is pivoted at 26 to the upper rear edge of the wall II. A spring 21 tends at all times toV move the cover 25 upwardly and away from the upper end of the housing. The cover is provided with a, depending member 28 which is located at approximately a right angle to the cover per se and a portion of the cover extends at right angles from the lower edge of the section 28 as indicated at 29. A lip or finger-piece 30 projects from the free end of the section 29. The .last-mentioned section is provided with a the between the partition I3 and the bottom I2. An. arm 40 extends at an acute angle upwardly and inwardly from the rod 32 and-is' provided with a horizontal extension 4|.. A pin 42 is 'secured to the horizontal extension 4| top 25 and has an enlargement 4 4 adapted to en; gage the outer surface of thesection 29 so that when the cover is raised by the spring 21 the reciprocating rod 32 will be elevated. The opening 43 "is slightly larger than the pin 42 t'oprovide for sufficient play of the pin in said opening when the top 25 is oscillated. i "i A cylinder 45, shown more particularly in Fig. 10, is secured to the front wall I4 of the housing I0 and is provided with an air vent 46 normally closed by a valve 41 which will permit air to enter said cylinder when a piston 48 is elevated'by means of a rod 49 connectedtothe horizontal extension 4|. The piston 48 is adapted to prevent rapid upward or downward movement of the top in order to give the moving elements sufficient time to perform their functions.

A shaft 50 has its outer end located within a bushing 5| which in turn is secured by means of an integrally formed plate 52 to the front wall I4. YThis bushingextends-through an opening 53 formed in said wall. A coil spring 54'surrounding the shaft 50 presses against a collar. 55 formed on the shaft 50 and against the rear wall of a pocket 56 in the bushing for urging the shaft to the right, as shown in Figs. 1 to 3, inclusive.

A conically-shaped member l51 is alsov connected to the shaft 58 and is adapted to be engaged by a cam member 58 connected to thereciprocating rod 32. An elongated toothed wheel 59 is connected to the shaft 50 at the inner end and a coin-supporting plate 60 issecured to the inner end of the wheel. A rackl, shown in Fig. 9, engages the elongated teeth of the wheel 59 so that when the rod 32 is reciprocated the-wheel 59, shaft 50 and the coin-supporting disc .60 will also be revolved. I'

The disc 68 isY provided with a peripheral flange 62 which is` adapted to engage the angular edge of the outer face ofthe coin for retaining the coin in proper position. The outer edge of the disc is provided With an annular lip 63 for a purpose which will be presently explained.

A plurality of `coin-detecting bars 10, shown more particularly in Fig. 14, which are considerably restricted in thickness, are placed in flat contact with each other and-are guidedA by a frame secured to the side walls of the housing I0. This frame consists of a top-bar1|r which extends entirely across thehousing and a pair of depending members 12 which engage the outer faces of the end bars. A'Ihe members 12retain the bars in close association at all times.

Each of the bars 10 is provided with cut-out portions 13 and these cut-out portions are adapted to be aligned to receive the cross bar 1| of the frame.V These cut-out portions provide front fingers 14 and rear fingers 15 and-'16 with the finger 16 of less width than the finger 15 so that and extends. through an opening 43 in the section 29 of the.

the front faces of the finger 16 are spaced rearwardly of the front faces of the fingers 15 for a purpose which will be presently explained.

Each bar 10 has a reduced rearward extension 11 or 18 and the rear ends are provided with passages 19 or 80 (Fig. 3). A slot 8| extends through the upper edge of each extension into its. respective opening 19 or 80.

A shaft 82 is supported by the side walls of the housing I0 anda plurality of weights 83 and 84 arepivotally mounted on said shaft. The weight 83 has a finger 85 projecting in through the slot 8| of the 'opening' 19 while a linger 86 projecting :from a'iweight 84 projects through a slot 8| into an opening `8|) in the extension 18.

It will be noted that not only the openings 19 and 80 are staggered in alternaten relation but the slots 8| andthe weights 83 and 84 are also staggered in the same relation.

A plurality of control bars 90 and 9| are slidably mounted on the shelf I5 `(Figs.` 1 to 3, inclusive, and'Figs. 13 and 14). extend upwardly from the shelf I5 and embrace the outer face of the two end bars 90 and 9| and maintain the bars in flat contact with each other.

:Each bar 90'is provided with an openingv 93 and a slot 94 extends from this opening to the outer lower edge of an extension 95 projecting fromthe bar 90. Each of the control bars 9| is provided with an extension 96 having an opening 91 and a slot 98. Each weight 93 at its upper end and in a line with the finger 85 or 86, as the case may be, is provided with a finger 99 or |00 which is adapted to bereceived 'respectively in the slot 94 or theV slot 98 so that these fingers project into their respective openings 93 or 91. Thus it will be seen that when the weights 83 are movedV backwardly at their upper ends that the sliding movement of the control bars 90 and 9| will'cause aY complementary movement of the bars 1|] or Vice. versa. l It will be noted that the openings 93 and 91 are staggered in alternate bars in the same relation-as are the openings 19 and 80 in the respective extensions 11 and 18 of the bars 10. This alternate arrangement places alternate slots in both the extensions 11 and 18 and 95 and 96 against a fiat portion of said extension to prevent the fingers at the opposite ends of the weights 83 and 84 from engaging the edges of adjacent slots and thus prevent the proper operation of the weights and likewise the bars 10, 90 and 9|.

It will be noted that the front ends of the bars 9U recede slightly from the front ends of the bars 9| so that the alternate bars in this series have their front ends located in staggered relation.- Slots I 06- and |01 formed in the upper edges of the bars 90 and 9| will, in an inoperative position, be disposed in staggered relation as shown in Fig. 14. When these control bars, however, are in operative position and the proper coin has been vplaced within thecoin-control mechanism-these slots will be aligned, as shown in Fig, 13,.-to receive the bar` |05 which normally is in a position to drop into they aligned slots at av predetermined point in the operation of the mechanism. l

Legs ||0 are secured to the outer ends of the bar |05, depend therefrom and are mounted in guides carried by the side walls 2| and 2|a. A lever ||'2 (Figs. 1 to 3, inclusive) is pivotally mounted at 3 on ears 4 extending from the rear wall of the housing. 'Ihe upper end ||5 of said lever is in a position to be engaged by a finger ||6 projecting from the underface of the A pair of posts 92` rsi cover 2| for moving the lever to the right in said figures. The lower end of the lever is received within a pocket I I1 formed in a sliding block IIB and pivoted to said block at |9. This block is slidably mounted on the partition I3. A spring |20, mounted on a pin |2I carried by a wall |22 formed at the iront end of the shelf II3, is adapted to press against a shoulder |23 formed on the front end of an extension |24 of the block II8.- The lower end of the coin slot or chute 20 is closed by a lip |25 projecting forwardly from the shoulder |23 and this lip also extends over a vertical slot |26 formed in the member 38 of the slidable `drawer 30. When the drawer is in the proper position the slot |26 will be in vertical alignment with the slot 20.

A trip lever |21 is pivotally mounted on a pin |28 which is carried by the side walls of the housing. This lever is provided with a iinger |29 which projects through a slot |30 in the shelf I3 and through a slot |3| formed "1n the block I8 when the slot |3| aligns with the slot |30. A second finger or keeper |32 projects fromV the underface of the lever |21 and is adapted to normally engage the front end of the slot |3| to prevent rearward movement of the block II8 as will be presently explained. The front end of the lever |21 is provided with a cross bar |33 which is adapted to be engaged by the lower ends |34 of the legs I|0 which are connected to the cross bar |05.

The drawer 39 is provided with a curved slot for a purpose which will be presently eX- plained. The rear section of the drawer is provided with an elongated pocket |40 in which is mounted a spring |4| which has one end in engagement with a shoulder |42 at the rear end of the pocket while the opposite end of the spring is in engagement with a collar |43 carried by one end of a slidable rod |44 which extends through a passage |45 in the rear wall II of the housing I6 and a disc or collar |46 is secured to the outer end of the rod and normally is engaged with the outer face of the wall II. The spring I4| maintains the drawer 39 in its inward position. It will be noted that the rod 32 (Figs. 1 to 3) projects through the passages 35 and 36 and prevents the removal of the drawer 39 when the cover plate 25 is in its downward position or is ascending towards its extreme upward inoperative position. When the top reaches its upward limit of movement, as shown in Fig. l, the rod 32 will be released from the passages 35 and 36.

The upper face of the drawer is provided with a groove |56 in which the free end of the finger |29 rides at times. groove is shown as being inclined to act as a cam member for engaging the free end of the nger |20 for forcing the finger upwardly to release the latch member |32 of the lever |21 from its engagement with the front wall of the slot |3| formed in the reduced portion |24 of the .block vI I8 Awhen the drawer 39 is withdrawn.

A pair of bell crank levers |52 are pivotall mounted on pintles |53 extending from the side walls 2| and 2|@l at opposite sides of the series of control bars 90 and 9|. One arm |54 of each of the bell crank levers is adapted to be received by a slot |55 formed in the upper ends of the legs |I0 which depend from the cross bar |05. The free end of the other arms of the levers |52, as shown at |56, are adapted to be engaged by the inner face of the descending top 25, as shown in Fig, 2, for rocking the lever for raising the cross bar |05 and the legs ||0 out of engagement The rear wall |5I of thisV with the cross bar |33 carried by the lever |21 so that the lever will be rocked and the latch member |32 will be moved into engagement with the front wall of the slot |3| and prevent the spring |20 from forcing the block I I9 to its rearward and inoperative position after the block has been moved forwardly.

A pair of levers |60, shown in dotted lines in Figs. 1 to 3, inclusive, and in full lines in Fig. 5, are pivotally mounted on pins I6I. Pins |62 carried by the side bars 12 of the cross bar 1| project through elongated slots |63 formed in the levers so that when the block |I8 is reciprocated these levers will be rocked and the free ends |64 of said levers will engage the rim or flange 63 of the coin holder 60 and jar the coin holder to cause the coin to be released from the iiange 62.

The front end of the selective bars 10, as shown more particularly in Figs. 5 and 14, are cut out or countersunk to form an intaglio into which will neatly iit that face of a nickel upon which the buffalo and indicia is cast. In other words when the nickel has been dropped through the slot 20 and is in the proper position, lit will neatly iit within this intaglio I 10. Due to the fact, however, that it is impossible for the operator to drop the coin so that the proper face will neatly rit within the intaglio the coin is revolved-until it does neatly fit. `While the device is shown to be operated in connection with the depositing of a nickel the intaglio may represent one face of a ten cent piece or a quarter and where there are three slots employed for the various coins in a coin-controlled telephone three of these casings may be applied side by side or three mechanisms may be employed in a single casing. While it is true that the slots in a telephone box or housing are close together it will be appreciated that the widths of the members 10, 00 andV 9| are restricted in width so that they can be operatively housed in a very small space and the width of each of the individual members 10, and 9| will be determined by the diameter of the coin employed.

In order to deposit a nickel 0r the proper coin into the operating mechanism the lip 30 of the cover 25 must be depressed so that the rod 32 will also be depressed until the inclined portion 40 of the rod will engage the walls of the slot 3,3 and since the rod 32 must be moved in a vertical line the sliding plate 34 will be moved rearwardly Y until the coin slot 34a aligns with the coin chute 20. At this time the slot 3| in the cover 25 will also be aligned with the slot 34a in chute 20 as will appear from Fig. 2. The coin then may be deposited through these aligned slots whence it will fall through the chute 20 and in alignment with the inner face oi the disc 60 and will rest upon the lip |25 of the slidable block IIB.

' As the rod 32 is moved downwardly the cam member 58 will engage the inclined walls of the member 51 and force said member to the left in Figs. l to 3, inclusive, against the tension of the spring 54 andthus the disc 60 which is rigidly connected with said shaft will likewise be forced to the left to open the coin chute 20 and the inner face of the disc 60 will be spaced from the outer faces of the bars 10 and in spaced relation with the intaglio |10. As the rod 32 is moved downwardly the rack 6I (Fig. 4) which meshes with the gear wheel 59 causes the disc 60 to be revolved idly and the lower end of the rod 32: will project through the passages 35 and 36 of the drawer 39 and prevent manipulation of said drawer. f It will be noted that the lower reduced end 32 of said rod is provided with an elongated slot |1| received by a pin |12 projecting from the front plate I4 will aid in guiding the rod in its downward movement and will maintain the rack in engagement with the gear wheel 59.

' A number of operations'are started when the cover plate 25 is moved down against the tension of the spring 21 and one of these operations is caused by the finger ||6 engaging the upper end I I5 of the lever I2 whereby the upper end of said lever is moved to the right in Figs. 1 to 3, inclusive, while the lower end is moved to the left. This causes the block I |8 to be moved to the left whereby the latch member |32 will drop into the slot |3| and engage over the front wall of said Slot and prevent rearward movement of the block against the tension of the coil spring |20. By this movement the lip |25 has been moved beneath the lower end of the chute 20 to maintain the coin I 15 within the slot and will prevent the coin from passing through the openings |26 and I26a. into the usual slot of the telephone box.

The block I I8 is moved forwardly in advance of the operation of any of the other elements because of the fact that the nger ||6 is normally in engagement with the upper end ||5 of the lever I I2. However, the cover plate 25 must be rocked through a predetermined angle beforethe slidable plate 34 is moved to align the passage 34a, with the chute 20 and before the levers |52 are rocked.

It must be borne in mind that if the proper coin had been placed in the chute 20 and had passed through the slots |26 and |26a into the slot of the telephone receiver housing the bar |05 would be resting within the aligned slots |06 and |01 of the control bars 90 and 9|., When the cover 25 is depressed suiciently the rear arms |56 of the lever |52 will be engaged by the top of the cover and said arms would be rocked to the right in Figs. 1 to 3, inclusive, so that the arms |54 of said lever will be raised and thus they will raise the cross bar |05 out of the slots |06 and |01 of the control bars 90 and 9|, so that these control bars will be free to be moved by the weights 83 and 84. When the cross bar |05 is raised the legs ||0 depending from said cross bar will also be raised, thereby freeing the lever |21 so that the rear weighted end of said lever will tend to fall by gravity and the latch member |32 will be in a position to fall into the slot |3| of the block |I8 because of the fact that the lever ||2 has moved the block |I8 forwardly so that the slot |3| will be in a position to receive the latch member |32. The weighted members 83 and 84 which are held by the control bars 90 and 9| will tend to fall rearwardly and rock on the pivot 82 so that the fingers 85 and 86 of said weights will rock forwardly and thus shift the bars 10 forwardly whereby the intaglio |12 will be in a position to press against the coin |15` When the iinger of the operator is released from the lip ,30 after the cover 25 has been lowered against the tension of the spring 21, the cover will be elevated and it will rise slowly due to the fact that the air cushioned piston 48 (Fig. 1) will pre-` vent rapid elevation of the cover. As the cover rises the rod 32 will likewise be raised and the rack (Fig. 4) will cause rotation of the gear wheel 59 and likewise the disc 60. As the bar 32 rises (Figs. 1 to 3, inclusive) the cam member 58 will be moved away from the conically-shaped member 51 so that the coil spring 54 will force the shaft 50 and the disc 60 to the right and press the coin |15 against the intaglio |10 and the coin will be engaged by the annular lip 62 of said disc whereby the coin will be revolved with the disc 60 until the inner face of the coin containing the embossed conguration of a buffalo will be neatly fitted within the intaglio. At this time the control bars 90 and 9| will be so positioned that the slots |06 and |01 will be aligned to permit the cross bar |05 to drop into said slots whereby the legs will drop the cross bar |33 carried by the lever |21 and thus rock the said lever and release the latch member |32 from the slot I3| whereby the spring |20 will move the block I I8 rearwardly and the lip |25 will likewise be moved rearwardly away from the bottom of the chute 20 to permit the coin when released to fall into the slot |26 and thus descend into the slot of the housing of thetelephone receiver. As the block ||8 moves rearwardly the upper ends of the levers |60 will be rocked forwardly and they will engage the ange 63 of the disc 60 and this impact will cause the coin to be released from the flange 62 of said disc so that the coin will be free to drop into the slot |26.

The bars 10, as has been explained, are moved forwardly by the tilting of the weights 83 and they will be maintained in a proper position so that all of the various sections of the intaglio which have been formed in the front ends of the bars 10 will be aligned to permit one face of the coin to be neatly tted within the intaglio.

It will be noted that when the control bars 90 and 9| and the bars 10 are in an inoperative position that the slots |06 and |01 Will be out of alignment, as shown in Fig. 4, and alternate fingers 15 on the bars 10 will be moved forwardly. When the slots |06 and 01 are not in alignment the cross bar I cannot operate to pass the-coin.

When a spurious coin, an incorrect coin, or a slug has been placed within the chute 20 it will drop into position to be engaged by the inner face of the disc 60 but due to the fact that it does not have the proper embossed conguration to be tted Within the intaglio the bars will not'be moved forwardly and therefore all of the weights 83 and 84 cannot be operated so that the control bars90 and 9| will not be shifted to the proper position to permit the cross bar |05 to drop within the slots |06 and |01 because said slots will be out of alignment as shown in Fig. 14. Thus the fingers and 16 will be in the position shown in Fig. 14 and the bars 10 will be maintained in an inoperative position so that the intaglio in effect is distorted. When this happens the block 8 will be retained in the position shown in Fig. 3 since the legs ||0 cannot drop downwardly to release the lever |21 and the latch member |32. The lip |25 will thus be located below the lower end of the chute and prevent the coin from dropping into the slot |26.

When the lip 30 is released the cover 25 will be automatically raised, thus removing the rod 32 from the passages 35 and 36 at the front end of the drawer 39 and it will be necessary for the operator then to pull upon the knob 39a against the tension of the spring |4| until the cam shoulder |5| engages the depending nger |29 of the lever |21 so that the linger will rise until it rests upon the top portion |5|a of the drawer 39 at the rear endthereof whereby the latch member |32 will be released from the front wall of the slot |30 so that the spring |20 will force the block ||8 rearwardly and thus remove the lip from below the lower end of the chute 20. At this time, however, the curved slot |35 will bein alignment with the lower end of the chute 20 and the coin will slide within said curved slot and be Vprojectedbeyond the free edge |2a of the bottom |2-A of the housing s'o that the spurious coin or slug will be discharged into the booth or into the room and will never reach the slot |26 or the slot |2611 which aligns with the usual coin slot of the housing of the telephone receiver.

The incorrect coin or slug will remain in the lower end of the chute 20 and be supported by the lip |25 until the drawer 39 has been moved to the left against the tension of the spring |4| and this drawer must thus be operated to permit the proper operation of the mechanism before a proper coin can be so positioned as to set the device in operation to permit the proper coin to pass through the slots |26 and |26a.

When the cover is released and if the proper coin has been inserted the finger H6 moves forwardly and upwardly away from the free end` of the lever ||5 to permit the spring |20 to force the block ||8 rearwardly and the cross bar |05 will remain in its locked position with respect to the control bars 90 and 9| until the cover Vis again depressed to actupon the levers |52 for raising the control bar |05. When the' cam member 58 has released the conically-shaped member 51 the spring 54 will move the disc 60 towards the front ends of the plates and when the coin has been properly engaged by the intaglio in the front ends of said plates the bars 10 will have been moved slightly to the left whereby the weights 83 will again beadjusted to their original positions and such movement willcause the control bars 90 and 9| to be properly positioned for the alignment of the slots |06 and |01 so that the cross bar |05 will drop into said slots. As soon as the bar |05, however, has been released the weights 83 and 84 will tilt rearwardly to cause misalignment of the slots |06 and |01 and a disarrangement of the bars 10 so that the sections of the intaglio will be placed out of alignment and thus deformed.

" The block I8 hasside walls ||8a which are guided by a cooperating means betweenv the shelf |3 and said walls.
